Because they have the outer electron shell full, with 8 electrons; this structure lead to a very low chemical reactivity.
Noble gases have a full shell of valence electrons, therefore are unlikely to gain or lose any since they are stable.
Green house gase
as noble as a king
No, it is a noble gas
Radon is a noble gas and is radioactive.
noble gases are elements and generally do not form cations due to the presence of completely filled valence shells.

No! Fluorine is the most "ignoble" gas, because it will bond to almost any other element, and chlorine is not far behind in its indiscriminate reactivity.
"Gases."
